What is ASTM B729 No8020 Alloy20 Seamless Pipe ?
 
ASTM B729 No8020 Alloy20 Seamless Pipe refers to a specific type of seamless pipe made from Alloy 20, which is a nickel-iron-chromium alloy with excellent resistance to corrosion, particularly in sulfuric acid environments. ASTM B729 is the specification standard set by the American Society for Testing and Materials (ASTM) for seamless pipes made from Alloy 20.
 
The No8020 designation indicates the specific composition of the alloy, which consists of approximately 34% nickel, 20% chromium, 3-4% copper, and small amounts of molybdenum, niobium, and iron.
 
Alloy 20 seamless pipes made in accordance with ASTM B729 are commonly used in various industries such as chemical processing, pharmaceutical, food processing, and power generation, where resistance to corrosion is critical. These pipes are known for their high strength, durability, and ability to withstand harsh environments.
